Deutsch DT / DTM / DTP / DTF Series Waterproof Connector – 2–12 Pin, Flange Mount

The complete Deutsch waterproof connector family in a single listing — covering all four primary series (DT, DTM, DTP, DTF) in flange-mount configurations for panel and bulkhead installation. Flange-mount connectors are permanently fixed to a panel via four mounting holes, creating a secure interface point where a mating harness plug connects and disconnects. This configuration is standard for cab-to-body connections on trucks and buses, junction box interfaces, and equipment panel connections in agricultural, marine, and industrial applications.

Deutsch Series Comparison

• DT series: Size 16 contacts, 13A per pin, 16–22AWG. Standard housing. The most widely used Deutsch series for general automotive and industrial harness wiring. IP67.
• DTM series: Size 20 contacts, 7.5A per pin, 20–24AWG. Compact housing (40% smaller than DT). For signal wiring and low-current sensors in space-constrained locations. IP67.
• DTP series: Size 12 contacts, 25A per pin, 12–16AWG. Larger housing. For high-current circuits: battery connections, motor power, high-draw actuators. IP67.
• DTF series: Size 16 contacts (same as DT), with integrated flange mount as standard. Designed specifically for panel-mount applications. IP67.

Flange Mount vs Inline — Application Guide

• Inline (standard DT/DTM/DTP): Both halves are on harness cables. No panel attachment. Use for harness-to-harness connections mid-run, sensor connections, and any application where neither connector half is fixed to a structure.
• Flange mount (this product): One half is permanently fixed to a panel, enclosure, or bulkhead. The mating harness plug connects and disconnects from the fixed receptacle. Use for: equipment panel interfaces, junction box connections, cab-to-body wiring penetrations, and any application where one connector half must remain fixed to a structure while the other is on a removable harness.

Frequently Asked Questions

What panel cutout size do I need for a Deutsch flange connector?

The panel cutout accommodates the connector body (not the flange). Approximate cutout sizes: DT 2–4 pin ≈ 22×22mm; DT 6–12 pin ≈ 28×28mm; DTM 2–4 pin ≈ 16×16mm; DTP 2–4 pin ≈ 28×28mm. Always verify against the specific connector datasheet before drilling — dimensions vary by pin count and series. The flange overlaps the cutout and is secured with M3 or M4 screws through the four mounting holes.

Can I use standard DT contacts in a DTF flange housing?

Yes. DTF housings use the same size 16 contacts as standard DT connectors. The contacts, wedge locks, and wire seals are interchangeable between DT and DTF housings of the same pin count. The only difference is the housing body — DTF has an integrated flange; DT does not.

How do I waterproof the panel penetration around a flange connector?

Apply a bead of silicone sealant (RTV, neutral cure) around the connector body where it passes through the panel cutout, before tightening the flange mounting screws. Alternatively, use a foam gasket between the flange face and the panel surface. The connector’s IP67 rating applies to the mated connector pair — the panel penetration requires separate sealing to maintain the enclosure’s IP rating.

What is the difference between DTF and DT with a separate flange adapter?

DTF connectors have the flange integrated into the housing body — a single-piece assembly. DT connectors can also be panel-mounted using a separate flange adapter (bracket) that clips onto the standard DT housing. The integrated DTF approach is more compact and provides a cleaner installation; the separate adapter approach allows standard DT connectors to be converted to panel-mount without changing the connector type.

Typical Applications

• Truck & bus: Cab-to-body wiring penetrations, trailer socket panels, body controller interfaces
• Agricultural equipment: Cab-to-implement wiring, junction box connections, sensor panel interfaces
• Marine: Bulkhead wiring penetrations, instrument panel connections, bilge and deck wiring
• Industrial: Control panel wiring interfaces, mobile equipment junction boxes, outdoor enclosure connections
• Motorsport: Firewall penetrations, dash panel connections, ECU enclosure interfaces
